The world is now warming faster than at any point in recorded history. Kirsty Wark talks to an historian, scientist and novelist about how to convey the story and impact of climate change.Floods, droughts, volcanic eruptions, hurricanes and solar activity have all shaped the natural history of our world from its formation. In The Earth Transformed the historian Peter Frankopan looks back at how the climate has constantly changed our world, but also at the impact of extreme climatic events on ancient human civilisations – often violent and epic in scale, from regime change to demographic decline. However, since the Industrial Revolution the balance has shifted and anthropogenic impacts on the climate can be seen more clearly. Peter Frankopan tells Kirsty Wark that learning lessons from the past has never been more important in tackling a precarious future.Professor Dame Jane Francis is Director of the British Antarctic Survey.

The philosopher Julian Baggini guides the listener in unpicking the tenets of humanism. His latest books is How to Think Like a Philosopher: Essential Principles for Clearer Thinking.Humanism may have relegated the divine to the side lines, but for the characters in Leila Aboulela’s novels faith and devotion are integral to their sense of themselves.
